NVIDIA RTX 3090 Ti vs NVIDIA RTX 5060 Ti 16GB for local LLMs
6 reports on the NVIDIA RTX 3090 Ti and 72 on the NVIDIA RTX 5060 Ti 16GB
Which is faster for local LLMs?
Nobody has reported the same model at the same quant on both cards yet, so there's no measured head-to-head. Memory bandwidth, which caps how fast a card can write, is 2.3x higher on the NVIDIA RTX 3090 Ti (1,008 GB/s on the NVIDIA RTX 3090 Ti, 448 on the NVIDIA RTX 5060 Ti 16GB).
